Went today with my wife and MIL. The verdict: no one liked it. 0 for 3. Their main complaint was that it was too long. I couldn’t disagree, this is a slog. It’s rare that I don’t like a musical, but even the song and dance numbers couldn’t hold my attention, maybe because for obvious reasons they are all gospel/blues based and it gets kind of one-note after a while.
I have not read the book or seen the original film, so I can’t comment on that aspect of it, but both my wife and MIL have. They felt it did not do the original story justice.
I will say it’s pretty to look at, the dance numbers are well-staged, the period sets are eye candy, basically from a technical perspective it is absolutely fine. But the characters and songs struggled and ultimately failed to hold my attention. I give it a C.
